Apart from Humming sound, we can found the following ways:-
1. OTI (Oil temperature indicator) shows the winding
temperature value
2.WTI (Winding temperature indicator)shows the winding
temperature value
but its not correct way because if we disconnect the TxR (after
some hours) charging both may show current values
